Question

if the body diagonal of cube crystal is 2.50A, the approximate edge length of the unit cell is​

Answer 1

Answer: edge length (a) =5

Explanation:

Given:-

r(body diagonal)=2.5A

a(edge length)=?

If we assume simple cubic unit cell then according to the relation between edge length (a)and radius or a body diagonal(r) which is :- r=a/2

Then ,

Putting the values in the above relation...

2.5=a/2

2.5*2=a

Thus, a =5.0

Answer 2

Answer:

edge length of unit cell

a=5.0A

Explanation:

concept- body diagonal of cube crystal is the radius of the crystal,formula used is r=a/2

where r= radius of body ( diagonal)

a= edge length of unit cell

given - diagonal of cube - 2.50A

find - edge length-?

explanation- r=a/2

2.50A= a/2

2.50*2= a

5.0A=a

a=5.0A
